The Sentek RT6 System has been designed to log
readings from multiple EnviroSCAN soil moisture
probes/sensors at pre-selected time intervals (as short
as 1 minute) for downloading into a computer. The
software provides graphical data manipulation for
analysis by trained growers, scientists or agronomists.
The Sentek RT6 System consists of :

logging facility

EnviroSCAN probes or EasyAG probes

access tube/top cap

soil moisture sensors

cabling

IrriMAX software
Appendix A illustrates the components that make up a
typical Sentek RT6 System and how it appears in the
field.
The central logging facility is connected by cable to
probes at each monitoring site. Probes can be located
within cable runs of up to 500 meters from the logger.
The logging facility supports 2 cable runs with each
run supporting up to 16 sensors. See Appendix B for
examples of configurations. The 16 sensors on each
run can be connected on 1 probe or spread across up
to 8 probes depending on application. With standard
components the array of sensors can extend to a soil
depth of 2.0 meters. Probes are available in standard
lengths of 0.5m, 1m, 1.5m, 2m. The system has the
capability of monitoring greater depths if required
upon special request. See Appendix C for examples
of probe configurations.
Downloading Downloading of data can occur either in the field via
a downloading cable to a notebook computer or in the
office by removing the logger and transferring the
data to a desktop computer. Additionally external
